MAX038CPP+

The MAX038CPP+ is one member of the MAX038 series.The MAX038 is a high-frequency, precision function generator producing accurate, high-frequency triangle,sawtooth, sine, square, and pulse waveforms with a minimum of external components. The output frequency can be controlled over a frequency range of 0.1Hz to 20MHz by an internal 2.5V bandgap voltage reference and an external resistor and capacitor. The duty cycle can be varied over a wide range by applying a ±2.3V control signal, facilitating pulse-width modulation and the generation of sawtooth waveforms.Frequency modulation and frequency sweeping are achieved in the same way. The duty cycle and frequency controls are independent.

Features of the MAX038CPP+ are:(1)0.1Hz to 20MHz operating frequency range; (2)triangle, sawtooth, sine, square, and pulse waveforms; (3)independent frequency and duty-cycle adjustments; (4)350 to 1 frequency sweep range; (5)15% to 85% variable duty cycle; (6)low-impedance output buffer: 0.1; (7)low-distortion sine wave: 0.75%; (8)low 200ppm/ temperature drift.Sine, square, or triangle waveforms can be selected at the output by setting the appropriate code at two TTL-compatible select pins. The output signal for all waveforms is a 2VP-P signal that is symmetrical around ground. The low-impedance output can drive up to ±20mA.

The absolute maximum ratings of theMAX038CPP+ can be summarized as:(1)V+ to GND:-0.3 to +6V;(2)storage temperature range:-65 to 150;(3)lead temperature:300;(4)continuous power dissipation:889mW;(5)operating temperature ranges:0 to 70;(6)maximum current into any pin:±50mA.Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.The MAX038 is a high-frequency function generator that produces low-distortion sine, triangle, sawtooth, or square (pulse) waveforms at frequencies from less than 1Hz to 20MHz or more, using a minimum of external components.Frequency and duty cycle can be independently controlled by programming the current, voltage, or resistance. The desired output waveform is selected under logic control by setting the appropriate code at the A0 and A1 inputs. A SYNC output and phase detector are included to simplify designs requiring tracking to an external signal source.
